Once the water cools, strain the leaves and pour the liquid into a spray bottle. This solution is safe for pets and furniture and can be stored in the refrigerator.
Bathe your pets in rosemary water solution post-shampoo, thoroughly comb their fur, and air dry for flea prevention. Spritz them daily with the solution for continued protection.
Alternatively, you can create a rosemary powder by crushing the leaves into fine dust and sprinkling it onto your pet or around the threshold of your property to ward off fleas.
